I have updated all kernel files EXCLUDING headers and source...what is importance of these files...if I did not update these files..is there any harm?

What other kernel files are there? Are you talking about the kernel itself?

yes I am talking about kernel itself. Actually I have updated the kernel from kernel-enterprise-2.4.9-e.3 to kernel-enterprise-2.4.9-e.35. During updation I have updated the following files
kernel-summit-2.4.9-e.8.i686.rpm
kernel-smp-2.4.9-e.8.i686.rpm
kernel-enterprise-2.4.9-e.8.i686.rpm
kernel-doc-2.4.9-e.8.i386.rpm
kernel-debug-2.4.9-e.8.i686.rpm
kernel-BOOT-2.4.9-e.8.i386.rpm
kernel-2.4.9-e.8.i686.rpm
The only files which I have not updated are the following
Kernel-source-2.4.9-e.8.i386.rpm
kernel-headers-2.4.9-e.8.i386.rpm

My question is: are these files must required to update kernel?

The first three look like three different kernels. In other words, the last one you installed is the one you're probably running. To double check which kernel version you're running type uname -r.

That was more by-the-by. As for source, you only need that if you plan to compile a kernel yourself at some stage (I would recommend this) and the headers you'll need if you wish to compile something against your current kernel like a graphics driver.

First of all thanks for so quick response.

sorry, it is typing mistake ..plz review my message again

I have not update source/headers files...Can my system work ok without these files or there is any harm..please reply in detail.

No I understood you just fine. I was just saying that I thought each of the first three files was a separate kernel.

I've already answered that question. Reread the second paragraph of my previous post.

sorry for disturbing again..last thing I want to know

You mean to update kernel as enterprise I only need to update
kernel-enterprise-2.4.9-e.35.i686.rpm and not need the following files to update:
kernel-summit-2.4.9-e.35.i686.rpm
kernel-smp-2.4.9-e.35.i686.rpm

Most probably yes. I can't see how you would bundle a kernel into more than one package. Like I said before, type uname -r at the prompt to see which kernel you're running.

thanks Mr. ADZ
Acutauly I have installed the following files
kernel-enterprise-2.4.9-e.35.i686.rpm
kernel-summit-2.4.9-e.35.i686.rpm
kernel-smp-2.4.9-e.35.i686.rpm
and during system booting I have to selected the 2.4.9-e.35enterprise from above three kernel...is it ok.

Yes that's OK as long as it's OK with you. You will not have any ill effects from this other than having to select the appropriate kernel at boot time.

it mean next time I only need to update the following one file to update kernel
kernel-enterprise-2.4.9-e.35.i686.rpm

Well, in short, yes. But I would recommend compiling you own (newer) kernel at some stage
